A great article here by Blaise Lucey at Movable Ink talks about Google’s ‘Mobile Friendly Test’ for websites. The general message from Google is “go mobile or go home – or risk getting what we can only imagine is going to be a severe SEO pummeling”.
However, this come from Google. Owner of Gmail. Gmail that does not support mobile responsive email. Gmail that’s forcing email devs to create a hybrid coding technique JUST to make emails work like they’re supposed to in your email app.
Google, you’re being a hypocrite. Sort out your email product so that it can handle what your demanding of websites.
